- Discus Trace ™ offers a wide spectrum of trace elements that are demonstrably necessary for good health and growth of the fish. Fish get their nutrients both from their food and from the water in their environment. Trace elements are normally depleted by consumption, oxidation and precipitation. That is why it is important to add these elements on a regular basis. Discus Trace ™ Contains only those elements that are scientifically proven necessary for fish.
